You are in Milling / End Mills/ Face Mills / Case Study - 7690VA12

Case Study: PowerMill90
PowerMill90 is a new family of 90° milling cutters and inserts offering higher feed rates than the competition while consuming less power.  This allows you to use the full capacity of your machine.
  • True 90° approach angle for accurate shoulder, slot and pocket milling
  • 0.433" cutting depth: high feed rate with a compact design
  • Choice of two body styles: standard and close pitch
  • Thick inserts for greater security in difficult conditions
  • Tool bodies with medium and close pitch teeth for maximizing metal removal
  • 4 grades offering for all materials operations

Field and lab test prove that the 7690VA12 can outperform the competition.
